1 Claim. (Cl. 55107) This invention relates to beet harvesting machines.

An object of this invention is to provide a machine of the character described, having highly improved means for cutting on the tops 2 The same comprises a horizontal frame H supported on front wheels l2 and rear wheels I3. On frame II is a second frame 14 shown in Fig. 5. On frame I i is supported a rotary shaft l which may be driven through a universal joint of the beets, and also for digging up the beets 5 connection with shaft I 8 obtaining power in any and harvesting them. suitable manner (not shown).

A further object of this invention is to pro- On shaft I5 is a gear ll. On frame l4 and vide a machine of the character described, havabove shaft i5 is a shaft 58. On shaft i8 is a ing a p W t0 ce e un d v d big 0 gear 59 meshing with gear ll. On said shaft is clogs, the plow being designed to go deep into another gear 20. Journalled in the frame I 4 the ground and loosen up the earth to facilitate and above shaft is is another shaft 2| carrying digging up the beets. a gear 22 meshing with gear 26. On shaft 2| A further object of this invention is to prois a bevel gear 23. vide in a machine of the character described, Also journalled in frame M are a pair of means to cut on the tops of the beets where the beets are high above the ground or substantially at the ground level.

Yet a further object of this invention is to provide in a machine of the character described, conveyors to take the cut off tops of the beets and'also the dug up beets to suitable receptacles or wagons.

Still another object of this invention is to provide in a machine of the character described, a digger for digging up the beets and'improved means for adjusting the level of the digger, and said machine also including means to bring the dug up beets onto the conveyor.

Yet another object of this invention is to provide a compact and durable machine of the character described, which shall be practical and efficient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claim.

In the accompanying drawing, in which is shown various possible illustrative embodiments of this invention,

Fig. 1 is a side elevational view of a machine embodying the invention;

Fig. 2 is a front end view of the machine;

Fig. 3 is a rear end view of the machine;

Fig. 4 is a vertical, cross-sectional view through the body of the machine;

Fig. 5 is an elevational, cross-sectional view illustrating a part of the machine;

Fig. 6 is a cross-sectional View taken on line -6 of Fig. 5;

Fig. 7 is a cross-sectional view taken on line .''i of Fig. 5; and

Fig. 8 is an end view of the structure shown in Fig 5.

Referring now in detail to the drawing, l0 designates a machine embodying the invention.

parallel horizontal shafts 25, 25a extending rearwardly of said frame. At the rear ends of shafts 25, 25a are bevel gears 26. The shaft 25 carries a sprocket gear 21 which is engaged by the endless chain 28, which also engages the smaller sprocket gear 29, on the shaft 2!. The shaft 25a carries a sprocket gear 21a, which is-engaged by the endless chain 28a, which also engages the smaller sprocket gear 29a, on the shaft I8, which is located immediately below the shaft 2|.

At the rear end of frame 5 l is a vertical frame 39 (see Figs. 3 and 5). Carried by frame so is a transverse shaft 3| loosely carrying bevel gears 32 meshing with the bevel gears 26.

Shafts 25, 25a carry sprocket wheels 34 connected by sprocket chains 35 to sprocket wheels 36 carried on a pair of horizontal shafts 3'5, 31a located below the shafts 25, 25a. On shaft 37a is a sprocket wheel 311) connected by sprocket chain 370 to a sprocket wheel 31d on a shaft 376 supported by the frame. On said frame is a second shaft 37]. On shafts 31, 31c and 31) are rollers 37g carrying a belt 40. Connected to the front ends of shafts 31, 37a by universal joints 33 are downwardly and forwardly inclined rods 44 connected by universal joints 45 to conical screw-like members 46 adapted to carry the dug up beets as will appear hereinafter onto a conveyor to be described later.

On shaft 25a is a sprocket wheel 50 connected by sprocket chain 55 to a sprocket Wheel 52 on a shaft 53 suitably journalled in the frame and disposed parallel to shaft 25a. On the sprocket wheel 52 are sprocket chains 55 for the purpose hereinafter appearing.

Fixed to the body of the machine is an upwardly and outwardly inclined chute 56. The upper end of the chute supports a shaft 51 on which there are mounted sprocket wheels 58. Carried by the sprocket wheels 58, 55 is a conveyor 60 adapted to move the dug up beets from the conveyor 40 upwardly within chute 56 to dump them on a wagon or any other suitable receptacle.

On the frame of the machine is a shaft 10 3 carrying a sprocket wheel II. On said frame is also an idler sprocket wheel 12. Fixed to one of the bevel gears 32 for rotation therewith is a sprocketwheelBiL n the frame .areupstanding arms 82. Supportedb t. the arms tflis'a shaft 83i On shaft 83 is a sprocket wheel 84. Extending over the sprocket wheel 80 and around sprocketwheels 'II and M is a sprocket chain 85 passing beneath and engaging the idler sprocket-wheel 82. Thus rotation of the bevel gear- 32--wil1 rotate shaft 83. Fixed to the machine is'a downwardly inclined chute 90. At the lower endmfitheechute;

is a horizontal shaft 9 I. On shaft 9! are sprocket wheels 92. On shaft 83sare sprocket wheels 93. Extending over the sprocket wheels 92, 93 is a sprocket type conveyor95 adaptedto-carrycuton" beettopsup the chute" 905 At the upper end of chutedilisa rearwardly-an'd downwardly inclined" chute 95 t0*di 1n1p the beet tops into a wagon or receptacle:
